Which is better for navigating and why ?

Thank you.

A PDA, or personal digital assistant, is any old thing which has a
screen and allows you to put your personal garbage into it's
built-in database and display it. It is not necessarilly a pocket
computer, which is what PPC stands for.

You would be hard put to navigate using a PDA which did not have an
operating system!
